Episode Overview
In Part 2 of their deep dive into peroxide-forming chemicals (PFCs), the Industrial Strength team—Jeff, Steve, and Randy—shift focus from the chemistry to the practical. This episode explores visual inspections, safe handling, and field testing methods for detecting peroxide buildup in lab and industrial environments. The crew also sets the stage for an upcoming third part packed with explosive case studies.
Segment Breakdown & Timestamps
00:29 – 01:42 | Intro & Podcast History
Reintroducing the topic with the signature humor—and realizing this is actually their third multi-part episode.
01:42 – 04:44 | Visual Inspection Basics
Why brown bottles are used, and what peroxide crystal formations might look like—from cotton candy wisps to golf ball-sized ice-like solids.
04:44 – 06:30 | Where to Check for Solids
Learn about common formation areas: bottle bottoms, cap threads, and edges—especially after opening and evaporative exposure.
06:30 – 07:58 | THF Case Study Intro
Previewing a bottle of THF with visible white peroxide solids—described as an “improvised explosive device.”
07:59 – 13:45 | Examples of Crystals & Testing Limits
Detailed visual indicators and why peroxide levels over 80 ppm can be hazardous—even lower for Class A chemicals.
13:45 – 15:01 | Peroxide Testing Tools
Quick reviews of:
15:05 – 16:42 | Recent Real-World Inspection
Jeff recounts a recent facility event where six 2-year-old bottles of peroxide formers were safely inspected and tested with zero detections.
16:43 – 21:20 | What If Peroxides Are Present?
Neutralization methods: sodium metabisulfite, sodium bisulfite, iron(II) sulfate, and dilution tactics to lower concentration for safe handling.
21:23 – 23:39 | Storage, Use, and Neutralization Refresher
Class A peroxides and why they’re rarely seen outside labs. Importance of planning, risk assessment, and not relying on “Shaky Joe” for delicate tasks.
23:41 – 25:25 | Tease for Part 3
Upcoming episode will feature case studies where things went very wrong. Stay tuned for real incident breakdowns and lessons learned.
